/**
 * OrderedTimeCodec encodes and decodes a UUID, optimizing the byte order for more efficient storage
 *
 * For binary representations of version 1 UUID, this codec may be used to reorganize the time fields, making the UUID
 * closer to sequential when storing the bytes. According to Percona, this optimization can improve database INSERT and
 * SELECT statements using the UUID column as a key.
 *
 * The string representation of the UUID will remain unchanged. Only the binary representation is reordered.
 *
 * PLEASE NOTE: Binary representations of UUIDs encoded with this codec must be decoded with this codec. Decoding using
 * another codec can result in malformed UUIDs.
 *
 * @deprecated Please migrate to {@link https://uuid.ramsey.dev/en/stable/rfc4122/version6.html Version 6, reordered time-based UUIDs}.
